Application filed July 3, 1916. Serial No. 107,382.

To all whom t may concern:

Be it known that I, EDGAR C. WHITE, al citizen of the United States, residing at Belmar, in the county of Monmouth and State of New Jersey, have invented certain useful Improvements in Plant-Boxes, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in plant boxes, one obj ect of the invention being the provision of a box for forcing vegetable or flower plants and which may be used within or without the hothouse.

A' further object of this invention is the provision of a box of this type which is simple, durable and inexpensive in construcplete top removed, and

Fig. 4 is a fragmentary detail showing cooperating cleats on the front and side plates.

, Referring to the drawings, the numeral 10 designates a single sheet of metal which provides the two side walls 11 and the rear wall 12 of the present box, the lower edges of such walls being provided with the in and upturned flanges 13, while the forward edges of the side walls are provided with the outturned flanges 14C.

The bottom 15 of the box is provided with the three downturned flanges 16S-which cooperate withthe flanges of the rear and side walls to maintain the bottom in position p while the forward edge is provided with the upturned lip 17.

rlhe front wall-18 of thebox is provided with the inturned edges 19 having each a cleat 20 which cooperates With the forward flanges of the side walls to slidingly attach thefront wall in'position, while the lower edge of the front wall is adapted to fit upon the bottom within the forward lip thereof.

In assembling this much of the box, the

bottom is slipped in place from above so that its flanges will coperate with the flanges of the rear and side walls, the front wall being inserted from above the upper edges of the side walls to slidingly engage the flanges thereof until its reinforced edge 21 is flush with the upper edges of the side and rear walls.

The cover carrying frame 22 of the present device is 4provided with the rim 23 which is adapted to be inserted within the upper open end of the box so that its outwardly extending reinforcing edges 24 will rest upon the upper edges of the front, rear and side walls of the box, and at the same time provide a clamping support for the screen top 25 of the cover.

Two opposite reinforced edges of the cover of the box are each provided with the U-shaped in cross section integral cleat 26 which slidably receives the sheet 27 of glass. Thus the glass may beremoved at will to permit of the circulation of air within the box, and will'when closingthe same, pro- 'duce an exceedingly practical cold frame for forcing plants.

In use, the ,present device is filled to the proper depth with soil and the seed planted therein, the complete cover having been previously removed. The complete cover is then placed in position and the seed is permitted to' germinate.

When the plants have reached suflicient size to transplant andit is desirable to removethem for transplanting, the complete cover is removedand the front wall of the box is also removed, thus permitting free access to the plants through the soil, so that a certain portion of the soil may be removed with each plant 'to insure a better transplanting operation without deleteriously affecting the plants.

`What l claim as new is l p A plant box, including rear andside walls made from a single sheet of material and each provided with a cleat upon its lower edge, the side walls being provided with cleats upon the front edgesthereof,"` a re movable bottom engaging the cleats upon the lower edge of therear and side walls, a

'ico

front wall having cleats for slidably engaging the cleats upon the forward edge of the side walls, a removable cover consisting of an open frameJ having a rim for insertion Within the rear, front and side walls of the box, limiting portions for engagement therewith, a screen attached to said limiting por-y tions, two of the opposite limiting Iportions being provided with flanges projecting therebeyond, and a removable sheet of transl0 parent material mounted in said flanges.

In testimony whereof I aflix my signature.

EDGAR o'. WHITE.
